SMOKE-IJACK.

SPECIFICATION forming part of. Letters Patent N0. 349,318, dated September 21, 1886.

Serial No. EEO-1,914. (No model.)

' of which the following is a specification.

My said invention relates to that class of devices known as slnokejacks, which con sist of a section of pipe with a flaring lower end connected to a stationary pipe secured in the roof of an engine-house or roundhouse,said flaring lower end being adapted to be dropped down over the upper end of the smoke-stack of 'a locomotive when in position in said house.

Said invention consists in devices for elevating and lowering said smoke-jack and securing it in the elevated or lowered position, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof; and on which similar letters of reference indicate similar parts, Figure l is a perspective view of the pipe, smoke-jack, and devices for operating said jack, the connection between said lever and smoke jack being indicated by dotted lines; Fig. 2, a detail sectional view through the lever and its keeper, showing the upper portion of the handle in elevation, as seen from the dottedline2 2 in Fig. 1; and Fig. 3, a horizontal sectional view, looking downwardly from the dotted line 3 3 in Fig. 2.

In said drawings, the portions marked A represent the smoke-pipe, B the smoke-jack, O the lever, D the handle, and E the keeper or catch-bar, with which projections on said handle may engage when said lever is pulled down, and the jack is consequently in elevated position. The pipe A and jack B are of substantially the usual construction, and need no special description. The lever G is mounted on a pivot or bolt, 0, which passes through. a bearing, a, secured to the side of the pipe, and itself passes through a slot in said bearing on said pipe to theinside, where it is connected by an appropriate link, 0, (see dotted lines in Fig. 1,) to said smokejack or appropriate ears thereon. The handle D consists, principally, of a straight rod having an appropriate hand-hold at the lower end and projections d at the proper point near its upper end. It is connected to the lever G by a clevis, D. lhe upper end of said rod extends through a hole in this clevis and has a head on its extreme upper end, which head. has a projection, d, on one side, which is adapted to strike the sides of the clevis as said rod is given a quartel turn in either direction. This projection is so arranged that when the rod is turned in one direction the projections (I will be in line wit-l1 the slot in the keeper or catch-bar E, through which said handle passes, and when turned in the other direction said projections will stand trans versely to said slot. The keeper or catch-bar E is securely attached to the pipe A and eX- tends out substantially the same distance as does the lever C. It is double,or has a slot formed therein through which the handle D passes. The operation is, when said lever is pulled down by means of said handle until the projections d are below said catch-bar, that by turning said handle saidprojections will stand transversely to said bar, and thus said bar will be kept from passing up through said slot, and the smoke-jack will be held in elevated position. WVhen it is desired to drop the smoke-jack onto the Smokestack of a locomotive, by simply giving this handle a quarterturn the engagement between the projections d and the catch-bar E are released and the handle and lever can be moved upwardly, permitting said smoke-jack to descend as desired.

Thus an efficient and simple means is provided for securing the smoke-jack in either of the desired positions.

Having thus fully described my said invention, what I claim as new, and desire to'secure by Letters Patent, is-

1. The combination of the sniokepipe, the smoke-jack, a lever pivoted to said smokepipe and connected to said smoke-jack, a'hair dle having projections and capable of being rotated, and a catch-bar provided with a slot through which said handle passes, whereby, when said projections are brought into engagement with said catch-bar, the smoke-jack will be held in elevated position, substantially as set forth.

2. The combination, with the lever for operating the smoke-jack, of the handle D, se cured to said lever by a clevis, D, said handle being provided with the projections 11 and In witness whereof I have hereunto set my 10 d, and the slotted catch-barE, through which hand and seal, at Indianapolis, Indiana, this said handle passes, substantially as set forth. 8th day ofJune, A. D. 1886.

3. The combination of the smoke-pipe, the

5 smoke-jack, a lever pivoted to said pipe and ANDREW W. QUACKENBUSII. [n s] connected to saidjack, a handle having projections or catches thereon, and a catch-bar In presence ofwith which said projections may be brought in C. BRADFORD, to engagement, substantially as set forth. CHARLES L. TIIURBER.
